IMPROVEMENT IN STOVE-PIPE DRUMS.

TO ALL WHOM IT MAY CONCERN: v

Be it known that I, J. A. Limit, of Thompson ville, Hartford county, State of Connectiouh have invented a new and useful Improved Radiator; and I'dohereby declare-'that the following is a full and clear description thereof, reference being'had to the accompanying drawings, and to the letters of reference marked thereon.

In the drawings' Figure 1 is aside-v iew-of my device, and

Figure 2 a detailed view of a part.

This invention consists of-an arrangement for radiating heat from stove-pipes, whereby the heat otherwise wasted through the chimney is saved and transmitted through the house.

In construction, 1' form my radiator of a number of cylindricai conicallycapped chambers, A A, &c., similar in shape to those shown invmy application of 1868, for stove-radiators, with the exception of these last having their bottoms open, whereas my piperadiators have their bottomsclosed, there beingno opening. to them except through pipes B and C, connecting each chamber to the stove-pipe, and the arrangement of which Iwill now describe. The lower pipes, C C, &.,- each enters its respective chamber at the lower part, and extends inside neariyto the top, while the pipes B enter near the top, and extend downwards, inside, to the bottom. A damper, D, is placed in the main pipe, between the entrance of the sets of pipe's'B and C.

The'operation of this device is as follows When the'fire is first kindled in the stove, and a good draught is needed, thedamperD is opened, and the ligatis allowed to pass straight up, as in ordinary cases. But after 7 the fire is well started, thedamperm'ay beshut, and the heat is obliged to pass around through the pipes B and C and the radiating-chambers A. In order to do this, thelheat passes through the lower pipes, C,"and is delivered into the chambers A, near thcir'tops inside. Onlythe lower portions of these chambers deliver into the mainpipe, as the pipes .13 open near, the bottom of the radiators, and consequently the cooler portion only of the enclosed air is carried up 'the fine, the tops of the radiating chanibers being always subjected to the hottest air passing. v

Now, having described my invention,'what I claim as new, and desire to secure by Letters Patent, is-

The arrangement of a number of radiating-chambers, -A, connected to the main pipe by means of the pipes B and C, and operated by means of a damper, D, the parts being combined and arranged together in the manner herein shown, and for the purpose set forth. I
